My mother has never been afraid to try new technologies. She had an Android tablet before me. She tried online dating before me. She was using computers before me, Mac and PC. When I told her about my Sous Vide Oven she was interested and asked me to build one for her. I wanted to test the waters and try a few dishes out first and after I cooked some tasty fish I ordered parts for a second oven controller. The second version will have a more powerful controller while my mom will get the easy-to-operate prototype. I've already written operating instructions for her.

Making a second version is exciting, not as exciting as the first, because I get to build on top of skills I've already exercised. I already know what I can do with a simple temperature controller but now I'm getting a temperature controller with PID control. The PID provides a more reliable heat source as opposed to just turning on the heater when the temp is too low.

The parts for the new oven controller came in the mail today so I can start hunting for new parts soon.

Enough background.

A piece of PVC was cut for the air tube. A ¾” hole was drilled in one of but only through one wall of the pipe. This hole will act to pass air in and out of the pipe. It was drill too close to the end and could have been drilled in the center instead. Another option will be to drill holes in the entire bottom of the PVC pipe. Caps were put on the ends of the pipe to test for length. The pipe will have to be trimmed as well.

Magnets were glued to one of the PVC caps. The magnets were held in place by putting matched magnets on both sides of a wooden clip board to ensure they would be on the same plane since the PVC caps purchased are rounded. Glue was applied to the magnets before setting the PVC cap in place. With the magnets still in place the procedure was repeated to attach magnets to a servo horn.

To do:
  • Get glueServo and platenServo working in program
  • Extend wires of waterServo
  • Buy 2 @ 1-1/2" PVC caps
  • Fix + Install air tube
  • Test + Debug
  • Revise documentation
